Does Sharks & Reefs level up Finspan? -TCbH Review

About Finspan: Sharks & Reefs, from BoardGameGeek:

Finspan: Sharks & Reefs adds to the variety of the core game with a focus on sharks and fish that live among coral reefs. This expansion introduces new coral reef habitats to your ocean mat and more incredible sharks-with fearsome new abilities! Players can now nurture colorful coral reefs in each of their ocean's three dive sites. Healthy reefs enable you to play powerful reef fish, unlock fish abilities, and score bonuses at the end of the game. Meanwhile, sharks scatter schools of young (to form even more schools elsewhere) and leave behind food scraps that any fish in your ocean can consume. To play this expansion, you need the Finspan core game. -description from the publisher
